Just my question. Whatever service it will come with, the full concept (phone AND iPod) will only work with that particular service.
Since Motorola sells phones using all the popular technologies, it's anybody's guess which they'll use for the intial release. I'm sure, if iTunes support becomes popular, that they'll release subsequent models with all the popular technologies (CDMA, GSM, PCS).
As for working with one service, obviously, the phone parts will only work with the network it (or its SIM card, in the case of GSM) are activated for. I don't expect the benefits/drawbacks of the phone parts to be any different from all other phones.
WRT the iTunes features, I'm not very optimistic. I can state with certainty that companies like Verizon will demand that it be crippled. I say this because that's what they did with my phone.
I use an Audiovox CDM 8600. This phone allows you to install screen-savers, wallpapers and ring-tones from attachments received in EMS text messages. Verizon's version of this phone, however, has the entire EMS facility disabled, in order to prevent you from doing this. They force you to buy these customizations through their over-the-air service at insane prices (like $5 for a 20-second ring tone.) (I am aware that you can install hacked firmware to put the missing features back, but you shouldn't have to do this.)
This is why the carriers are all opposed to a proper iTunes phone. They don't want you to install your ripped CDs into the phone. They don't even want you to pay the iTMS $0.99 price for a song. They want to charge you lots more - probably in the range of $3-5 each.
Of course, Motorola and Apple are refusing to allow this. They know that if people end up paying 50% of the price of an album, in order to install a single song, nobody will use the service and people will start associating the name "iTunes" with "overpriced."
